Please put anything Revit related in the Rhino.Inside - Revit forum category.
The Revit 2025 is still wip and requires the Daily or Service Release Candidate to install. If you have other versions of Revit these are available for download in the Rhino.Inside.Revit options located on its Revit Ribbon.
I’ve sent you a private link in case you don’t have any other Revit Version.
